Multivariable analysis (Table 6) showed that ΔTSH (TP2-TP1) is a significant predictor of hypothyroidism (OR 1.3, 95% CI 1.07–1.57, p = 0.007) together with Anti-Tg Ab positivity (OR 9.3, 95% CI 0.99–87.95, p = 0.051), even though this predictor has borderline significance. Here, TG is linked to hypothyroidism.
